Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00124 | $0.02233 |
| Opus 5 | $0.00062 | $0.01117 |
| Sonnet 5 | $0.00025 | $0.00447 |
| Haiku 4.5 | $0.00012 | $0.00223 |
Grade A, and why
video2dsprite scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to video2dsprite — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Video2dsprite (Grok Build only)
Convert a base 2D character image into dense animation sprites using Grok Build's native video tools.
base still → image_to_video (in-place motion) → extract frames → chroma key → sample/normalize → strip / grid / GIF
Platform gate (read first)
| Runtime | Supported? |
|---|---|
| Grok Build (xAI) | Yes — requires image_gen / image_edit + image_to_video (or reference_to_video) |
| Codex / Claude / other agents | No — they lack Grok video tools. Tell the user this skill is Grok Build only and offer $generate2dsprite instead |
If image_to_video is missing from the tool list, stop and explain. Do not fake motion with code-drawn frames.
This skill is an optional denser-motion path. It does not replace $generate2dsprite:
Use $generate2dsprite when… |
Use $video2dsprite when… |
|---|---|
| Crisp pixel sheets, fixed grids, identity-critical heroes | User wants denser intermediate poses / smoother feeling loops |
| Attack/cast body sheets, prop packs, engine atlases | Experimenting with video-sourced run/walk/idle motion |
| Production default for most game sprites | User explicitly asks for video → frames → sprites |
Video softens pixels, drifts identity, and leaves chroma fringes. Always QC; for production heroes, prefer $generate2dsprite unless the user wants the video look.

What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
